Bonomi’s S250 series stainless steel in-line check valves are NSF 61/372-certified for potable water and lead-free applications. Available in six sizes from 1/2" to 2", Bonomi S250 series check valves feature a cold-formed 316 stainless steel body that gives users the highest Cv at the lowest cost. The metal forming process allows an improved flow profile inside the valve body to minimize head loss. It also eliminates machining for reduced manufacturing cost. Booth: C6131
